Adjust to a comfortable seating posi-
tion that still allows you to reach the
accelerator/brake pedal safely. The
position should be as far to the rear as
possible, consistent with ability to
properly operate controls.
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and
the child is not properly secured in the child
restraint.i
When moving the seat, be sure that
there are no items in the footwell or
behind the seats
the cup holder next to the armrest
is removed (

Warning!G
In case of an accident, liquid electrolyte may
escape the mirror housing if the mirror glass
breaks.
Electrolyte has an irritating effect. Do not al-
low the liquid to come into contact with
eyes, skin, clothing, or the respiratory sys-
tem. In case it does, immediately flush af-
fected area with water, and seek medical
help if necessary.
!
Electrolyte drops coming into contact
with the vehicle paint finish can only be
completely removed while in their
liquid state and by applying plenty of
water.
Warning!G
Exercise care when using the passen-
ger-side exterior rear view mirror. The mirror
surface is convex (outwardly curved surface
for a wider field of view). Objects in mirror
are closer than they appear. Check your in-
terior rear view mirror or glance over your
shoulder before changing lanes.

matic transmission is in positionP
i
With the SmartKey removed and the
driver’s door open, a warning sounds if
the vehicle’s exterior lamps are not
switched off.
Warning!G
To prevent possible personal injury, always
keep hands and fingers away from the door
openings when closing the doors. Be espe-
cially careful when small children are
around.
Before closing doors, make sure there is no
possibility of someone getting caught in a
door during closing.
Warning!G
When leaving the vehicle, always remove the
SmartKey from the starter switch, take it
with you, and lock the vehicle. Do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle. Unsuper-
vised use of vehicle equipment may cause
an accident and/or serious personal injury.

71 Safety and Security
Occupant safety
Emergency tensioning device (ETD),
seat belt force limiter
The seat belts for the front and rear outer
seats are equipped with emergency ten-
sioning devices and belt force limiters.
The ETD is designed to activate in the
following cases:
in frontal or rear-end impacts exceed-
ing a preset severity level
if the restraint systems are operational
and functioning correctly, see
1indicator lamp (
page 62)In an impact, emergency tensioning
devices remove slack from the belts in
such a way that the seat belts fit more
snugly against the body.
Belts should not be worn twisted. In a
crash, you wouldn’t have the full width
of the belt to manage impact forces. The
twisted belt against your body could
cause injuries.
Pregnant women should also use a
lap-shoulder belt. The lap belt portion
should be positioned as low as possible
on the hips to avoid any possible pres-
sure on the abdomen.
Never place your feet on the instrument
panel, dashboard or on the seat. Always
keep both feet on the floor in front of the
seat.
i
The ETDs for the front seats will only
activate if the respective front seat belt
is fastened (latch plate properly
inserted into buckle).
The ETDs for the rear outer seats will
activate with or without the respective
seat belt fastened.
Warning!G
An emergency tensioning device (ETD) that
was activated must be replaced.
When disposing of the emergency tension-
ing device, our safety instructions must be
followed. These are available at your autho-
rized Mercedes-Benz Light Truck Center.
!
Do not place objects heavier than
20 lbs (9 kg) on the front passenger
seat. This could cause the passenger
front airbag and, with the seat belt
fastened to secure the object, the ETD
on the front passenger side to deploy in
a crash which exceeds the system’s
deployment threshold.

80 Safety and Security
Driving and safety systems
In this section you will find information on
the following driving safety systems:
ABS (Antilock Brake System)
BAS (Brake Assist System)
4-ETS (Electronic Traction System)
EBB (Electronic Brake Booster)
ESP (Electronic Stability Program)
ABS
The ABS regulates the brake pressure so
t h a t t h e w h e e l s d o n o t l o c k d u r i n g b r a k i n g .
This allows you to maintain the ability to
steer your vehicle.
The ABS is functional above a speed of ap-
proximately 5 mph (8 km/h) independent
of road surface conditions (as long as the
differential locks are not engaged).
At the instant one of the wheels is about to
lock up, a slight pulsation can be felt in the
brake pedal, indicating that the ABS is in
the regulating mode. Keep firm and steady
pressure on the brake pedal while experi-
encing the pulsation.
i
In winter operation, the maximum ef-
fectiveness of the ABS, ESP, EBB, and
4-ETS is only achieved with winter tires
or snow chains as required.
Warning!G
The following factors increase the risk of ac-
cidents:
Excessive speed, especially in turns
Wet and slippery road surfaces
Following another vehicle too closely
The ABS, BAS, ESP, and 4-ETS cannot
reduce this risk.
Always adjust your driving style to the pre-
vailing road and weather conditions.
Warning!G
Do not pump the brake pedal. Use firm,
steady brake pedal pressure instead. Pump-
ing the brake pedal defeats the purpose of
ABS and significantly reduces braking effec-
tiveness.
